Question: What do
I do to check that all of my archive logs were successfully
written to the archived redo log filesystem?
Answer: This script will allow you
to check your archived redo logs.
select
arch.thread#
"thread",
arch.sequence#
"last sequence received",
appl.sequence#
"last sequence applied",
(arch.sequence# -
appl.sequence#) "difference"
from
(select
thread#,
sequence#
from
v$archived_log
where
(thread#,first_time ) in
(select
thread#,
max(first_time)
from
v$archived_log
group by thread#))
arch,
(select
thread#,
sequence#
from
v$log_history
where (thread#,first_time)
in
(select
thread#,max(first_time)
from
v$log_history
